1. FIELD OF THE INVENTION

The present invention relates to a protein and composition comprising the protein for inhibiting or reducing lipases and phospholipase enzymes in body fluids, cells, and tissues. The protein as described in the present invention and the composition comprising of the same are useful for the prevention or treatment of clinical manifestations and diseases caused as a consequence of lipase and phospholipase enzyme activities in the body fluids, cells, and tissues.

2. DESCRIPTION OF THE PRIOR ART

Lipases and phospholipases are key control elements in mammalian metabolism. They share many common features that set them apart from other metabolic enzyme classes, most importantly their association with “two-dimensional” substrates, i.e., lipid droplets, lipoproteins, phospholipid layers, biomembranes, and the resulting implications for their cleavage mechanism and regulation.

The pancreatic lipase (PL) is believed to be effective in causing a partial hydrolysis of triglycerides to obtain fatty acids and monoglycerides that, together with the bile acids, form complexes, which are then absorbed through the intestinal mucosa. Hepatic lipase (HL) and lipoprotein lipase (LPL) are the two major lipolytic enzymes responsible for the hydrolysis of triglycerides and phospholipids present in circulating plasma lipoproteins. Both lipases are attached to the vascular endothelium via cell surface proteoglycans. HL is primarily involved in the metabolism of chylomicron remnants, intermediate density lipoproteins, and high-density lipoproteins, whereas LPL catalyzes the hydrolysis of triglycerides from chylomicrons and very low-density lipoproteins. In addition to their traditional function as lipolytic enzymes, HL and LPL appear to serve as ligands that mediate the interaction of lipoproteins to cell surface receptors and/or proteoglycans.

Accumulation and distribution of triglyceride-rich lipoprotein-associated fatty acids at extra-hepatic sites is facilitated by LPL. The enzyme is also involved in several non-lipolysis associated functions, including the cellular uptake of whole lipoprotein particles and lipophilic vitamins. The tissue-specific variations of LPL expression have been implicated in the pathogenesis of various lipid disorders, obesity, and atherosclerosis. LPL expressed by cells of the vascular wall, particularly macrophages, have identified additional actions of the enzyme that contribute to the promotion of foam cell formation and atherosclerosis. Development of drugs specifically acting on the cholesteryl ester transfer protein and lipoprotein lipase systems, are being explored.

Over the past several years significant advances have been made in our understanding of new, alternative mechanisms by which HL and LPL modulate lipoprotein metabolism and the development of atherosclerosis in vivo. Advances have also been made in our understanding of the intravascular metabolism of triglyceride-rich lipoproteins. It is now known that the complex extracellular interactions of triglyceride-rich lipoprotein-associated apolipoprotein E, lipoprotein lipase, and hepatic lipase with heparan sulfate proteoglycans and lipoprotein receptors facilitate the hepatocellular uptake of triglyceride-rich lipoproteins. Recent studies have also revealed that the intracellular fate of internalized triglyceride-rich lipoproteins is highly complex. The dissociation of triglyceride-rich lipoprotein components within intracellular endosomal compartments involves the recycling of apolipoprotein E, whereas the remaining lipid core associated with apolipoprotein B is susceptible to lysosomal degradation.

The high incidence of atherosclerosis in diabetic patients has been correlated with LPL activity in macrophages. Accumulating evidence indicates that LPL produced by macrophages in the vascular wall may favor the development of atherosclerosis by promoting lipid accumulation within the lesion.

The potential of lipases as drug targets for the treatment of metabolic syndrome and cardiovascular disorders is increasingly recognized. It is now believed that the front line therapy for diseases related to lipid absorption and metabolism should be to inhibit or reduce lipase activity in the body fluids, cells, and tissues.

Lipase inhibitors have been reported from various natural products, especially from microbial sources. The example of such inhibitors include lipstatin and Panclicins A-E from Streptomyces species or their synthetic derivatives that inhibit the hydrolysis of triglycerides and cholesterol esters (Hochuli et al., Lipstatin, and Inhibitor of Pancreatic Lipase, Produced by Streptornyces Toxytricini, II. Chemistry and Structure Elucidation, J. Antibiot. (Tokyo), 1987 August, 40(8):1086-91; Fernandez et al., Effects of Tetrahydrolipstatin, a Lipase Inhibitor, on Absorption of Fat from the Intestine of the Rat, Biochim. Biophys. Acta., 1989 February, 20, 1001(3):249-55; Yoshinari et al, Panclicins, Novel Pancreatic Lipase Inhibitors, II. Structural elucidation, J. Antibiot. (Tokyo), 1994 December, 47(12):1376-84) and is being used for treatment of obesity (U.S. Pat. No. 5,540,917). Besides, a number of molecules have been identified from plant sources including tannins isolated from Cassia nomame (U.S. Pat. No. 5,629,338). LPL has been shown to be involved in the pathogenesis of atherosclerosis (Mead et al, Lipoprotein Lipase, a Key Role in Atherosclerosis?, FEBS Lett., 1999 November, 26, 462(1-2):1-6). Inhibition of LPL is believed to prevent the atherosclerotic process (Zimmerman et al., Lipoprotein Lipase Mediates the Uptake of Glycated LDL in Fibroblasts, Endothelial Cells, and Macrophages, Diabetes, 50, 1643-1653, 2001).

Phospholipases specifically act on and hydrolyse membrane phospholipids and generate mediators implicated in signal transduction and inflammatory processes. The role of phospholipase A2 (PLA2) is well known in the generation of arachidonic acid, which is responsible for leukotriene and prostaglandin synthesis; PLA2 inhibitors have been proposed as drugs for variety of inflammatory and degenerative diseases. Lipoprotein-associated phospholipase A2 has been shown to be involved in atherosclerosis and its inhibition is being proposed for its treatment (Leach et al., Lipoprotein-Associated PLA2 Inhibition—A Novel, Non-Lipid Lowering Strategy for Atherosclerosis Therapy, Farmaco, 2001 January-February, 56(1-2):45-50).

5. EXAMPLES Example 1

Isolation of Lipase Inhibitory Protein from Moringa Seeds:

100 gm-powdered seeds were soaked in 1 litre MQ water for 48 hrs at room temperature. The extract was filtered through Whatman filter paper. The filtrate was concentrated using lyophlizer (−50° C.) for two days to get the protein isolate. Protein was estimated by using Bradford method.

Result: 10 mg powdered contained 494 μg protein.

Example 2

SDS-PAGE (17%) was performed with the protein isolated from Moringa seeds and stained with Coomassi blue. 5±1 kd band was cut and transferred to a siliconized tube and washed and destained in 200 μL 50% methanol overnight. The gel pieces were dehydrated in acetonitrile, rehydrated in 30 μL of 10 mM dithiolthreitol in 0.1 M ammonium bicarbonate and reduced at room temperature for 0.5 h. The DTT solution was removed and the sample alkylated in 30 μL 50 mM iodoacetamide in 0.1 M ammonium bicarbonate at room temperature for 0.5 h. The reagent was removed and the gel pieces dehydrated in 100 μL acetonitrile. The acetonitrile was removed and the gel pieces rehydrated in 100 μL 0.1 M ammonium bicarbonate. The pieces were dehydrated in 100 μL acetonitrile, the acetonitrile removed and the pieces completely dried by vacuum centrifugation. The gel pieces were rehydrated in 20 ng/μL trypsin in 50 mM ammonium bicarbonate on ice for 10 min. Any excess trypsin solution was removed and 20 μL 50 mM ammonium bicarbonate added. The sample was digested overnight at 37° C. and the peptides formed extracted from the polyacrylamide in two 30 μL aliquots of 50% acetonitrile/5% formic acid. These extracts were combined and evaporated to 25 μL for MS analysis.

Lipase Inhibitory Activity of Moringa Seed Protein in the Presence of Synthetic Substrate:

Lipase Assay:

Enzyme assay was performed by method described by Winkler and Stuckmann, 1979, with modification where there was use of pancreatic lipase. Assay was designed, using a 96-well format. The substrate used in this assay was p-nitrophenol palmitate (Sigma, Cat No-N-2752). 4.5 mg of p-nitrophenol palmitate was dissolved in 200 μl of N, N-dimethylformamide (Sigma, Cat No, D-4551) and volume made up to 10 ml with 0.1 M Ph 8.0-phosphate buffer. Lipase (Sigma, Cat No, L-3126) sample was prepared by dissolving the enzyme in 0.1M-phosphate buffer at a concentration of 5mg/ml. The reaction mixture consisted of substrate solution-150 μL; phosphate buffer (pH 8.0, 0.1 M) −40 μl and lipase solution-10 μl. The reaction mixture was incubated at 37° C. and optical density was measured at 405 nm after incubation. Enzyme activity was presented in the form of international unit (KU). One enzyme unit of lipase is defined as that quantity releasing 1 nm of free phenol from the substrate (p-nitro phenol palmitate) ml/min under the standard assay condition (Winkler K. W. and Stuckman M, 1979 Glycogen hyaluronate and some other polysaccharides greatly enhances the formation of exolipase by Serratia marcescens, J. of Bacteriology 138: 663-670). It is derived from standard graph of p-nitro phenol.

Lipase Inhibition by Moringa Seed Protein:

Inhibition assay was performed in a dose dependent manner. The concentration of the protein checked 40 μg-0.156 μg/ml reaction mixture. The assay was similar to assay described above except 40 μl of inhibitor solution was used instead of phosphate buffer in control. Released p-nitro phenol was recorded at 405 nm. Enzyme inhibition was presented in the term of percentage inhibition simply on the basis of change in international unit (IU), which was calculated from standard graph.

Inhibitory Activity of Moringa Seed Protein in the Presence of Natural Substrate:

Lipase activity was also measured by titrating free fatty acids liberated in the reaction mixture by following a modified method of “Ishiia C et al., 1988, Inhibition of lipase by proteins and their inhibitory mechanism, Nippon Shokuhin Kogyo Gakkaishi, 35 (6), 430-439. The reaction was performed in tubes by shaking at 37° C. for 30 min. the reaction mixture was prepared with 1.5 ml of Mcllvaine buffer, pH-7.0, 0.24 ml of olive oil, and 0.5 ml of inhibitor solution and water all in final volume of 5.5 ml . After 5 min preincubation, the reaction was then started by adding 0.5 ml of enzyme solution (5.0 mg) . The reaction was then stopped by the addition of 10 ml mixed solution of n-propyl alcohol: petroleum ether (1:4), and mixture was then shaken vigorously for 2 min 1 ml of upper layer was pippetted and titrated with 0.02 M alcoholic KOH using phenolphthalein as an indicator. The standard reaction mixture was prepared as described except that buffer substituted the inhibitor solution. Fatty acid released μM/min under standard assay condition was considered as one international unit (W) of enzyme.

Conclusion: Moringa seed protein was able to inhibit the pancreatic lipase during the hydrolysis of natural substrate olive oil.

Example 5

Effect of Trypsin on Lipase Inhibitory Activity of Moringa Seed Protein:

The lipase inhibitory activity was performed after tryptic cleavage of Moringa seed protein. The isolated protein (500 μg/ml estimated by Bradford method) was incubated with trypsin (0.5%) in 50 mM, Tris buffer, pH-9.0 & sample buffer for 24 hrs at 37° C. in 1:1:2 ratio. After incubation all the samples were allowed for thermal inactivation at 70° C. for 10 min. The lipase inhibitory assay was performed as described earlier except 40 μl of test solution (trypsin treated/untreated) was used instead of phosphate buffer in control. Released p-nitro phenol was recorded at 405 nm. Lipase activity was presented in the term of percentage inhibition simply on the basis of change in international unit (IU), which was calculated from standard graph.

Result
